Operating principle

— Dynamic. "Conventional", or coil, dynamic microphones use a system of diaphragm (membrane) and coil, which is placed in a magnetic field. From sound vibrations, the membrane, and with it the coil, set in motion, and an electrical signal is generated in the coil. Such models are relatively inexpensive, durable and reliable, besides, they cope well even with very loud and harsh sounds; they are also smaller and lighter than another type of dynamic microphone, the ribbon microphone (see below). Their main disadvantage is poor efficiency at high frequencies.

Dynamic (tape). A variation of the dynamic microphones described above, in which the membrane is connected not to a coil, but to a thin (a few microns) metal tape, hence the name. Historically, this is the first type of microphone with a dynamic principle of operation, however, due to a number of shortcomings, it gradually lost its wide popularity, giving way to coil options. Such shortcomings are, first of all, large dimensions and large mass, complexity and high cost in production, as well as a very low output impedance, which complicates the work with amplifiers. At the same time, tape models have extremely high sound fidelity over the entire frequency range, which allows them to be used in recording studios, at high-class concerts, etc. Most modern models of this type are professional models, in particular, studio models (see "Purpose")....r>
— Condenser. The name of this type is due to the fact that the microphone is actually a capacitor, in which the sensitive membrane (usually made of a metallized polymer) plays the role of one of the plates. Due to the vibration of the membrane (under the action of sound vibrations), the distance between the plates changes and, accordingly, the capacitance of the capacitor — these capacitance fluctuations provide an electrical signal. Condenser microphones have a uniform sound transmission over the entire frequency range, with a minimum of distortion, due to which this technology has found wide application in professional audio equipment. Note that for the operation of such a device, additional power is required — the so-called "phantom" (standard voltage — 48 V). However, this cannot be called an unequivocal disadvantage, because. amplifiers, receivers and other high-end appliances are often made with this requirement in mind. But of the obvious shortcomings can be called a high price, sensitivity to shock and strict requirements for temperature and humidity; the latter makes condenser microphones less suitable for outdoor use.

Condenser (tube). A specific variation of the condenser microphones described above. They use the same sound extraction principle (with all the advantages and disadvantages), however, the amplifying element in such models, in accordance with the name, is built on vacuum tubes. Technically, such an amplifier introduces more distortion into the signal than a transistor one, but these distortions give the sound a characteristic colour that is pleasant to many listeners. Simply put, the same notorious “warm tube sound” is obtained; At the same time, achieving such an effect using a microphone is cheaper than using a tube amplifier, and for a number of technical reasons, this option often turns out to be optimal. Almost all tube microphones have a studio purpose (see above). Their main drawback is the high price (several times more than that of "ordinary" capacitor counterparts). In addition, such models have their own nutritional characteristics; to supply energy, a special adapter is usually supplied in the kit, which is also responsible for controlling additional functions such as changing the beam pattern.

— Electret. By design, such microphones are similar to the condenser microphones described above, however, their design includes a plate of the so-called electret — substances with special electrical properties. This provides a number of advantages: electret microphones can be used outdoors without much difficulty, they can be made more compact, and such models are cheaper to manufacture; at the same time, the sound transmission quality can be quite comparable with condenser ones. As a result, this technology is found in a wide variety of models — from miniature lapel and simple computer to studio (see "Purpose"). Also note that electret microphones also require external power, but not always phantom 48 V — for some varieties, a small amount of power is enough, which can be provided by a compact battery or powered by a 3.5 mm mini-Jack cable.

Sensitivity

Sensitivity describes the signal strength at the output of a microphone when it processes a sound of a certain volume. In this case, sensitivity means the ratio of the output voltage to the sound pressure on the membrane, expressed in decibels. The higher this number, the higher the sensitivity. Note that, as a rule, values in decibels are negative, so we can say this: the closer the number is to zero, the more sensitive the microphone. For example, a -38 dB model outperforms a -54 dB model in this parameter.

It should be borne in mind that high sensitivity in itself does not mean high sound quality - it only allows the device to “hear” a weaker sound. Conversely, low sensitivity is not an unequivocal sign of a bad microphone. The choice for this parameter depends on the specifics of the application: a sensitive device is useful for working with low sounds and in cases where it is necessary to capture the smallest nuances of what is happening, and a “weak” microphone will be convenient at high sound volume or, if necessary, filter out extraneous weak noises. There are models with sensitivity adjustment(and for models with a headphone output , headphone volume control may be provided).
